Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed May 21, 1904. Serial No. 209,040.

To all/ lull/077D it may concern:

Be it known that I, BURTON R. STARE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Car-Journals, of which thefollowing is a specification.

My invention relates particularly to means for retaining oil in andexcluding dust from journal-boxes at the inner ends thereof; and myprimary object is to provide more efiicient and desirable means foraccomplishing said purposes than any heretofore known.

The invention is illustrated in the accompanying drawings, in which-Figure 1 represents a broken vertical longitudinal section of a journaland journal-box equipped with my improvements, the section being takenas indicated at line 1 of Fig. 5; Fig. 2, a section of the detacheddust-guard;

Fig. 3, an enlarged broken section of the dust guard, taken as indicatedat line 8 of Fig. 6; Fig. 4, a similar section showing the dustguardcollapsed, as when in the dust-guard cavity of the journal-box; Fig. 5,a section taken as indicated at line 5 of Fig. 1; Fig. 6, an outer faceview of the improved dustguard; Fig. 7, an inner face view of the outerplate of the dust-guard, and Fig. 8, an inner face view of the innerplate of the dust-guard.

In the preferred construction, A represents a journal-box, B a journal,and C a dustguard confined in a cavity or slot (0 at the inner end ofthe journal-box.

The inner end of the journal-box has a journal-opening a, which isintersectedby the dust-guard cavity in the usual manner. The outer walla of the cavity a is equipped on its inner surface with an annular bossa having a milled surface (0*, provided with annular oil-grooves a. Thewall of the opening in the outer wall a is beveled at its lower portion,as shown at a. The inner end of the journal-box is of sufficient widthto allow spaces between the side portions of the annular boss and theside walls of the journal-box,

as shown in Fig. 5. This permits the boss to be readily milled andinsures a close joint with thedust-guard. The opening in the inner wallof the guard-cavity is cut lower than the opening in the outer wall, aswill be understood by observing the relative heights of the points a anda in Fig. 1.

The dust-guard comprises an outer plate 0,

having a circular perforation 0' and an annular boss 0 at the innersurface of the plate, an inner plate 0 provided with an opening 0*,receiving the boss 0 screws 0 connecting the plates near the fourcorners thereof, and coilsprings 0, confined between the plates andencircling the screws. The plate 0 is provided near the four cornersthereof and on the inner surface of the plate with bosses 0 surroundedby annular channels 0 and affording sockets for the corresponding endsof the springs 0".

The bosses are perforated to receive the screws 0 and the perforationsare countersunk at their outer ends to receive the heads of the screws,as shownin Fig. 3. The plate 0 is provided with corresponding sockets 0for the springs and With threaded perforations for the screws 0". Thescrews are turned in to the proper distance and then riveted, as shownin Fig. 3. The wall of the journalreceiving perforation c of the plate 0is provided at its side and top portions with fillings of Babbitt metal0 and the wall is provided with continuous circumferential grooves 0 Theplate 0 is provided at its inner surface, near the four corners thereof,with lugs 0 whose inner surfaces project flush with the inner surface ofthe annular boss 0 At the lugs 0 the outer surface of the plate 0 isprovided with depressions 0 The inner surface of the boss (0 of thejournal-box is milled, as stated above, and the outer surface of theplate 0 is milled, so that a close joint is provided. In addition theannular grooves 06' become filled with oil and act as packing-rings toprevent passage of oil or dust. The bore of the plate 0 snugly receivesthe shoulder of thejournal, as shown in Fig. 1, and the annular grooveso receive oil, which prevents the egress of oil and the ingress of dust.To secure a true surface at the outer face of the outer plate 0, theplate is first secured upon the bed of a planer with the outer surfacedown, and the inner surfaces of the lugs 0 and the annular boss 0 areplaned. The plate is then turned over and clamped at the depressions 0and the outer surface of the plate planed. The plates are preliminarilyplaced together with the lugs c passing into corresponding marginalrecesses 0 in the plate 0, and the screw-receiving holes in the twoplates are simultaneously bored. The construction insures the properrelation of the plates when the parts are assembled and facilitates theoperation of assembling the parts. The inner surface of the plate 0 isrecessed at its bottom portion, as indicated at 0 to enable the returnof oil from the dust-guard cavity a to the interior of the journal-box.

hen the parts of the dust-guard are assembled, the plates are normallyseparated by the springs to such an extent that the dust-guard isconsiderably thicker than the space which receives it when in workingposition. When the guard is forced into position, the springs arecompressed, the guard being collapsed, or rendered thinner, as shown inFig. 4. The springs are sufliciently strong to exert quite a highpressure, preferably more than one hundred pounds, so that the outerplate of the dust-guard will be forced firmly against the annular bossa". It now will be understood that when oil is thrown against thedust-guard from thejournal-box, as in rounding a curve. theliquid-pressure acts with the springs to hold the plate 0 firmly seatedagainst the boss with which the outer wall of the dust-guard cavity isequipped. Moreover, inasmuch as the inner wall of the dust-guard cavityis cut lower than the outer wall, the source of oil from the inside ofthe dust-guard will not rise as high as the top of the lower portion ofthe outer retaining-wall. Furthermore, the bevel surface a, will serveto prevent water from entering the journal-box and causing the lighteroil to escape from the journal-box. As stated above, the bevel surface0, also tends to prevent sand or dust from entering the journalboX.

I have shown the journal-box provided with a boss (Z at the upperportion of the dust-guard cavity, and this boss has its top surfaceplaned and surmounted with a flanged cap or cover CZ, which is firmlysecured in place by screws (Z It is usually desirable to insert a blockof wood above the dust-guard and below the cap (Z', although none isshown in the drawings. The purpose of providing the antifrictionbearings0 at the upper and side portions of the packing-ring is to prevent unduewear at the points which are most subjected thereto owing to thestarting and stopping of trains and to the jolting action which occurswhen the trains are running. The springs o are practically effective torelieve the journal from the weight of the dust-guard, and the upperbearing of Babbitt metal is an additional precaution to prevent unduewearing.

Changes in minor details of construction within the spirit of myinvention may be made. Hence no undue limitation should be understoodfrom the foregoing detailed de scription.

What I regard as new, and desire to secure by Letters Patent, is-
